Cisco Webex iOS SDK

CocoaPods Travis CI license

The Cisco Webex iOS SDK makes it easy to integrate secure and convenient Cisco Webex messaging and calling features in your iOS apps.

This SDK is written in Swift 4 and requires iOS 10 or later.

Table of Contents

Install

Assuming you already have an Xcode project, e.g. MyWebexApp, for your iOS app, here are the steps to integrate the Webex iOS SDK into your Xcode project using CocoaPods:

  1. Install CocoaPods:

    gem install cocoapods
  2. Setup CocoaPods:

    pod setup
  3. Create a new file, Podfile, with following content in your MyWebexApp project directory:

    source 'https://github.com/CocoaPods/Specs.git'
    
    use_frameworks!
    
    target 'MyWebexApp' do
      platform :ios, '10.0'
      pod 'WebexSDK'
    end
    
    target 'MyWebexAppBroadcastExtension' do
        platform :ios, '11.2'
        pod 'WebexBroadcastExtensionKit'
    end
  4. Install the Webex iOS SDK from your MyWebexApp project directory:

    pod install

Usage

To use the SDK, you will need Cisco Webex integration credentials. If you do not already have a Cisco Webex account, visit Webex for Developers to create your account and register your integration. Your app will need to authenticate users via an OAuth grant flow for existing Cisco Webex users or a JSON Web Token for guest users without a Cisco Webex account.

See the iOS SDK area of the Webex for Developers site for more information about this SDK.

Example

Here are some examples of how to use the iOS SDK in your app.

  1. Create the Webex instance using Webex ID authentication (OAuth-based):

    let clientId = "$YOUR_CLIENT_ID"
    let clientSecret = "$YOUR_CLIENT_SECRET"
    let scope = "webex:all"
    let redirectUri = "Webexdemoapp://response"
    
    let authenticator = OAuthAuthenticator(clientId: clientId, clientSecret: clientSecret, scope: scope, redirectUri: redirectUri)
    let webex = Webex(authenticator: authenticator)
    
    if !authenticator.authorized {
        authenticator.authorize(parentViewController: self) { success in
            if !success {
                print("User not authorized")
            }
        }
    }
  2. Create the Webex instance with Guest ID authentication (JWT-based):

    let authenticator = JWTAuthenticator()
    let webex = Webex(authenticator: authenticator)
    
    if !authenticator.authorized {
        authenticator.authorizedWith(jwt: myJwt)
    }
  3. Register the device to send and receive calls:

    webex.phone.register() { error in
        if let error = error {
            // Device not registered, and calls will not be sent or received
        } else {
            // Device registered
        }
    }
  4. Use Webex service:

    webex.spaces.create(title: "Hello World") { response in
        switch response.result {
        case .success(let space):
            // ...
        case .failure(let error):
            // ...
        }
    }
    
    // ...
    
    webex.memberships.create(spaceId: spaceId, personEmail: email) { response in
        switch response.result {
        case .success(let membership):
            // ...
        case .failure(let error):
            // ...
        }
    }
    
  5. Make an outgoing call:

    webex.phone.dial("coworker@acm.com", option: MediaOption.audioVideo(local: ..., remote: ...)) { ret in
        switch ret {
        case .success(let call):
            call.onConnected = {
                // ...
            }
            call.onDisconnected = { reason in
                // ...
            }
        case .failure(let error):
            // failure
        }
    }
  6. Receive a call:

    webex.phone.onIncoming = { call in
        call.answer(option: MediaOption.audioVideo(local: ..., remote: ...)) { error in
        if let error = error {
            // success
        }
        else {
            // failure
        }
    }
  7. Make an space call:

    webex.phone.dial(spaceId, option: MediaOption.audioVideo(local: ..., remote: ...)) { ret in
        switch ret {
        case .success(let call):
            call.onConnected = {
                // ...
            }
            call.onDisconnected = { reason in
                // ...
            }
            call.onCallMembershipChanged = { changed in
                switch changed {
                case .joined(let membership):
                    //
                case .left(let membership):
                    //
                default:
                    //
                }                
            }            
        case .failure(let error):
            // failure
        }
    }
  8. Screen share (view only):

    webex.phone.dial("coworker@acm.com", option: MediaOption.audioVideoScreenShare(video: (local: ..., remote: ...))) { ret in
        switch ret {
        case .success(let call):
            call.onConnected = {
                // ...
            }
            call.onDisconnected = { reason in
                // ...
            }
            call.onMediaChanged = { changed in
                switch changed {
                    ...
                case .remoteSendingScreenShare(let sending):
                    call.screenShareRenderView = sending ? view : nil
                }
            }
        case .failure(let error):
            // failure
        }
    }
  9. Post a message:

    webex.messages.post(personEmail: email, text: "Hello there") { response in
        switch response.result {
        case .success(let message):
            // ...
        case .failure(let error):
            // ...
        }
    }
    
  10. Receive a message:

    webex.messages.onEvent = { messageEvent in
        switch messageEvent{
        case .messageReceived(let message):
            // ...
            break
        case .messageDeleted(let messageId):
            // ...
            break
        }
    }
    
  11. Screen share (sending):

    11.1 In your containing app:

    webex.phone.dial("coworker@acm.com", option: MediaOption.audioVideoScreenShare(video: ..., screenShare: ..., applicationGroupIdentifier: "group.your.application.group.identifier"))) { ret in
        switch ret {
        case .success(let call):
            call.oniOSBroadcastingChanged = {
                event in
                if #available(iOS 11.2, *) {
                    switch event {
                    case .extensionConnected :
                        call.startSharing() {
                            error in
                            // ...
                        }
                        break
                    case .extensionDisconnected:
                        call.stopSharing() {
                            error in
                            // ...
                        }
                        break
                    }
                }
            }
            }
        case .failure(let error):
            // failure
        }
    }

    11.2 In your broadcast upload extension sample handler:

    override func broadcastStarted(withSetupInfo setupInfo: [String : NSObject]?) {
        // User has requested to start the broadcast. Setup info from the UI extension can be supplied but optional.
        WebexBroadcastExtension.sharedInstance.start(applicationGroupIdentifier: "group.your.application.group.identifier") {
            error in
            if let webexError = error {
               // ...
            } else {
                WebexBroadcastExtension.sharedInstance.onError = {
                    error in
                    // ...
                }
                WebexBroadcastExtension.sharedInstance.onStateChange = {
                    state in
                    // state change
                }
            }
        }
    }
    
    override func broadcastFinished() {
        // User has requested to finish the broadcast.
        WebexBroadcastExtension.sharedInstance.finish()
    }
    
    override func processSampleBuffer(_ sampleBuffer: CMSampleBuffer, with sampleBufferType: RPSampleBufferType) {
        switch sampleBufferType {
            case RPSampleBufferType.video:
                // Handle video sample buffer
                WebexBroadcastExtension.sharedInstance.handleVideoSampleBuffer(sampleBuffer: sampleBuffer)
                break
            case RPSampleBufferType.audioApp:
                // Handle audio sample buffer for app audio
                break
            case RPSampleBufferType.audioMic:
                // Handle audio sample buffer for mic audio
                break
        }
    }

  12. Receive more video streams in a meeting:

    class VideoCallViewController: MultiStreamObserver {
        ...
        var onAuxStreamChanged: ((AuxStreamChangeEvent) -> Void)? = {
            ...
            switch event {
            case .auxStreamOpenedEvent(let view, let result):

                ...
            }
        }
        
        var onAuxStreamAvailable: (() -> MediaRenderView?)? = {
            ...
            return self.mediaRenderViews.filter({!$0.inUse}).first?
        }
    
        var onAuxStreamUnavailable: (() -> MediaRenderView?)? = {
            ...
            return self.mediaRenderViews.filter({$0.inUse}).last?
        }
        
        
        override func viewWillAppear(_ animated: Bool) {
            ...
            // set the observer of this call to get multi stream event.
            self.call.multiStreamObserver = self
            ...
        }
    }
    

Migration from Cisco SparkSDK

The purpose of this guide is to help you to migrate from Cisco SparkSDK to Cisco WebexSDK.

Assuming you already have an project integrated with SparkSDK.

  1. In your pod file:

    remove previous SparkSDK: pod 'SparkSDK'

    add WebexSDK: pod 'WebexSDK'

  2. Go to project directory, and run:

    pod install
  3. Replace sdk import info for your code:

    Replace in project scope:

    "import SparkSDK" => "import WebexSDK"

  4. If you using story board for UI:

    Change meida render view's module in "Indentity inspector":

    "SparkSDK" => "WebexSDK"

Usage

API changes list from SparkSDK to WebexSDK.

Description SparkSDK Use WebexSDK Use
Create a new instance let spark = Spark(authenticator: authenticator) let webex = Webex(authenticator: authenticator)
"Room" Client renamed to "Space" Client spark.rooms.list(roomId:{rooomId}) webex.spaces.list(spaceId:{roomId})
"SparkError" renamed to "WebexError" let error = SparkError.Auth let error = WebexError.Auth

Recomand to replace variables containing "spark" with "webex" in project code.
